Although the aviation physiologist has been long acquainted with the principles of powered flight and the effects of increased acceleration, he was not aware of the phenomenon of reduced acceleration and weight until very recently. Moreover, it was not always sufficiently clear which physical quantities were involved in the entire spectrum of these biodynamic processes, and which designations, terms, and symbols are adequate for the description of their effects.

These concepts may also be of benefit for the preparation of experiments involving motion simulators and zero-G devices. In all cases of freely moving bodies, the force of inertia compensates the gravitational force at any point of their trajectory, thereby creating the so-called "agravic" or "gravity-free" state.

e. , the gravitational-inertial relationship extended to at least the molecular level of the masses involved, their technological and biological effects generally should be the same wherever and whenever they occur; that is, within or outside of any gravitational field, and during free fall as well as during free ascent.
